Special constructions

Extensions to include customer-specific axle designs or special constructions are possible at short notice.

 

 

 

 

 

 

All front axles are available with the options of rack and pinion steering or a recirculating ball and nut steering gear.

 

The axle spring can be connected to any part of the wheel suspension in all front and rear axles.
